The "C" stands for create, the "R" for retrieve, the "U" for update, and the "D" for delete. CRUD is used to denote these conceptual actions and does not imply the associated meaning in a particular technology area (such as in databases, file systems, and so on) unless that associated meaning is explicitly stated.

At present, we have deployed ArchiveSpark in a stand-alone machine due to the version conflict of Spark. The version of Spark for running ArchiveSpark is 1.6.0 or 2.1.0. Unfortunately, the Spark version is 1.5.0 in our Hadoop Cluster. Therefore, we need to upgrade the cluster and then deploy our framework to process big collections.

This involved importing spark.sparkContext and calling sparkContext.read.json(path) to load our data. We tried using Python’s JSON libraries on this loaded object, but this was unsuccessful. We discovered that the sparkContext.read.json(path) call loads the data from the HDFS (Hadoop Distributed File System) into a DataFrame object.

Spark uses a data structure called a Dataframe which is a distributed collection of data organized into named columns. These named columns can easily be queried and filtered into smaller datasets which could then be used to generate visualizations.

The first step was to create bi-grams of the data we had in PySpark’s dataframe. The Pyspark library has a feature where it turns string data into a string array of bi-grams. The initial plan was to convert our dataframe of articles into a dataframe of bi-grams, but since PySpark’s library transformed the articles (which are in string) into ...
